I have a PHP script within which I have embedded a Perl program using system command.
The Perl program is as under;
<code>
#!/usr/bin/perl system("perl /opt/lampp/htdocs/matepred/blast/bin/scriptforblastcompleterun.pl sequence.txt uniprot_sprot.fasta > out"); system("perl /opt/lampp/htdocs/matepred/blast/bin/convert.pl"); system("perl /opt/lampp/htdocs/matepred/blast/bin/format.pl > output"); system("/opt/lampp/htdocs/matepred/blast/bin/svm-predict output pssm.scale.model pssm.predict >pssm.out");
<code>
The first four commands of this program run correctly, but the last one does not run. This one contains an executable named "svm-predict".
I guess this is because I need to grant special permissions to the PHP user for running executables.
Please suggest.
